He's an actor, a comedian, a TV game show host, a Classic FM presenter - and a classical baritone. But what's Alexander's guilty pleasure?
She'd love to meet Elgar for a coffee, have him round for dinner - and Nimrod is also her favourite tune. Here, the Smooth Classics presenter reveals all.
If you could sit down and have a coffee with one great composer, who would it be?
Elgar - I would love to find out more about where he found the inspiration for the emotion and passion you can hear in his music.
Favourite ever interviewee or guest?
Gareth Malone - a man whose passion for getting the nation singing and really helping people find their voices shine through in every conversation you have with him.
Who would be your four perfect dinner party guests?
If it were possible I would have Elgar, Oprah Winfrey, the Queen and Nelson Mandela - four people with amazing stories to tell.
What’s your guilty pleasure?
Coffee - I love it and drink way too much. Skinny Cappuccino to go please!
Most memorable concert you attended?
Andrea Bocelli in Central Park - it's one of the biggest open air concerts I've been to (pictured above). It rained almost the whole way through but it was still fantastic. The rain stopped for the encore, 'New York New York' which he sang with special guest Tony Bennett, with a full moon shining over the stage and 70,000 concert goers - a great night.
Which superpower would you like to have?
To me cooking really well sounds like a superpower. It's not my forte - I burn salad.
What's your favourite snack when you're feeling a bit peckish in the Classic FM studio?
Chocolate of any kind.
All-time favourite piece of music?
Elgar's Nimrod is a front runner for an all-time favourite. It's just perfect to unwind with or for a moment of reflection - Handel 's Zadok the Priest is a close second - with a cup of coffee in the morning it can set you up for the day. I also love to run and my track of choice at the moment is Pharrell Williams' Happy . He is such a talent. I understand why Hans Zimmer wants him to be the man to soundtrack his life.
All-time favourite book?
Fahrenheit 451 by Ray Bradbury. I still treasure the first copy of this book I read as a student with all my notes and scribbles in it.
All-time favourite film?
The Wizard of Oz and It's a Wonderful Life. I've lost count of the times I've watched both of them over the years. I can't help it - I love a feel good film!
